Jenny surveyed the library. “This place looks festive.” She grinned. “ You've even hung up mistletoe.”

“Ah…yes,” said Giles. “Did you know that as well as being associated with ancient Druidic fertility rituals, mistletoe was often used as an ingredient in wards, and actually has a repelling effect on several species of demon, similar to garlic on vampires?”

Jenny raised her eyebrows.

“Did you know that, these days, mistletoe is traditionally used to give people an excuse to kiss someone who might otherwise spend the entire Christmas season alone in a library researching demons?”
